About Environmental Test Chambers

It is critical for manufacturers to locate product flaws before their product reaches the market. By testing your product in a CSZ test chamber you can:

• Reduce Product Development Time
• Increase Customer Confidence
• Ensure Product Quality & Reliability
• Forecast Life Expectancy
• Reduce Costs
• Increase Profitability
• Reduce After Sales Service

Environmental test chambers are used for various types of testing such as prototype evaluation, research & development testing, production testing, accelerated stress testing, reliability testing, failure analysis, and any other application where environmental simulation is needed.

Environmental test chambers can simulate virtually any type of environmental condition such as temperature, humidity, altitude, vibration, solar, wind & rain, dust, etc. Test chambers are available from 1.2 cubic foot of interior workspace and up with temperature range capabilities of -300°F for cold chambers all the way to +1000°F for the extreme high temperature conditions. All chambers contain stainless steel interior with a powder-coated finish.

Types of Test Chambers

Listed below are types of test chambers available in the marketplace along with a brief definition of each chamber type/use:

• Highly Accelerated Life Test (HALT) involves a combination of temperature, shock and vibration to locate a product weakness and assess the life of a product
• Highly Accelerated Stress Screening (HASS) involves fast temperature cycling and is performed on production units.
• Thermal Cycling involves subjecting an object to extreme changes in temperature within an environmental chamber while ramping up and down in temperature.
• Temperature Chambers simulate temperature and tests the effects on a product over a range of temperature conditions. Temperature cycling may be performed while combining environments such as humidity, altitude, and vibration.
• Humidity Chambers simulate humidity and tests the effects on a product over range of humidity conditions. Humidity tests may be performed with or without temperature.
• Bench top test chambers are used when testing small items and take up minimal floor space.
• Thermal Shock chambers thermally shock and stress a product as a result of rapid temperature changes from extreme cold to hot environments.
• Liquid-To-Liquid Thermal Shock chambers immerse a part/assembly in hot and cold fluids. Product is transferred between hot and cold baths without contamination.
• Air-To-Air Thermal Shock chambers typically involve transferring the product from a hot chamber to a cold chamber. Configurations include two zone, three zone, and double duty.
• AGREE Vibration Chambers can produce fast temperature changes. These chambers have removable floors and integrate with a variety of electrodynamic shakers for vertical and/or horizontal vibration. Temperature and/or humidity environments are also simulated in conjunction with vibration.
• Altitude chambers simulate the effects of low pressure and are capable of altitudes of up to 200,000 feet above sea level.
• Environmental Stress Screening (ESS) chambers are designed to test products for highly accelerated stress testing and fast ramp rates.
• Walk-in chambers are environmentally conditioned rooms that may be configured to almost any size or footprint. Types of walk-in chambers include modular and welded (unitized) construction. Welded types are ideal for high temperature testing.
• Drive-in chambers are similar to walk-in chambers and are designed for vehicle testing. Temperature, humidity, vibration, and solar may be simulated.
